Relativity goes to the dogs

Chad Orzel, an associate professor of physics, has a new book, How to Teach Relativity to Your Dog, in which he again tries to simplify a difficult subject matter in a way that even a canine can understand. The book is a follow-up to Orzel’s well-received How to Teach Physics to Your Dog, which introduced the world to his brainy 10-year-old mutt, Emmy.
